Polynomial (Graph Settings)
A polynomial curve can be fit to the data in an x-y Graph trace. When the check box is selected, this curve is calculated and shown on top of the data points in the Graph trace.
The Polynomial Order can be specified, and the calculated polynomial coefficients can be read from the Graph Results table or from the Graph trace's Data Header. For more information about the curve-fit line, including how to export the line, see the Coef N topic.
